great, congratulations both!
Strange that according to Stefan's forest grabber the PSK transmission was carrying on long after the scheduled end of sequence (19:01:22 ?).
Will now attempt to decode here as well.

I was impatient, with still 5549.6 seconds left
to go I decoded the message easily,
'CQ CQ DREAMERS BAND DE DK7FC IN JN49IK PSE KK'
Carrier S/N: 25.03 dB in 10.3 uHz
Eb/N0 = 0.1dB with constant reference phase. I'll
let the decoder go through a full phase search, it
may find a better decode with a phase pattern that
is closer to the diurnal. Later I'll decode the
full transmission, we should get a better Eb/N0.
That must be one of the longest messages decoded.
Only needed 1.8 GByte RAM so within reach of home
... decoder has finished the phase search. No
improvement on the 0.1dB so looks like LWPC is close
to the mark with its phase prediction.
